We present a brief review on charge transport in organic field-effect transistors (OFETs), which is necessary to further design nanostructured devices. Dielectric physics is used to explain charge transport of these organic devices in the steady and transient states. We clearly show the influence of internal fields on charge accumulation and transport, and propose models for potential distributions across the OFET channel. Potential drop on the electrodes (the contact resistance) is also discussed and its control is described. Improvement of OFET performance is explained in terms of the design of device dimensions, materials and operation regime.
